HOW is the C64 version more accurate? It actually ISN'T! It's totally made up BASED on the original.

I am sure you have never played the original arcade version and assumed the C64 version is accurate.

I just said it sounds awful And yes, the arcade version sounds awful too, while the c64 "conversions" sound perfect. I would much rather have tunes that are pleasing to the ear than "accurate" versions which sound like that.
